progressed in order to obtain the items provided by its quartermaster.
Gaining reputation with this faction is done through World Quests and the
process can be sped up using the Contract: Talanji's Expedition item,
which is provided by players with Inscription.

As of Patch 8.1, a new item has been added to the Island Expedition vendor
in exchange for 100 Seafarer's Dubloon called Golden Beetle
which grants 250 reputation with the Talanji's Expedition. This provides a
repeatable catch up mechanic for this reputation.

1.1. The Talanji's Expedition's Contract

As with most other reputations, the Talanji's Expedition have a contract which
grants reputation for each World Quest finished while under its effects. This

Note that the effect of Contract: Talanji's Expedition will persist until you use another
faction's contract. Should you never do so, the effect will stay on permanently
for Talanji's Expedition.
